Ray, I found something interesting in the archive. In 2001 Terry Haines posted this about the inner joint becoming internally dislocated.
"Inner CV is the one you use the ties on,the 'tripod' will slide out if you dont,the 3 bearings will fall into the boot inside and you will never get it re-engaged without removing the boot."
Perhaps I allowed the axle to move at too great an angle and caused this to happen.
